Abstract

PCT No. PCT/FR97/00303 Sec. 371 Date Dec. 11, 1998 Sec. 102(e) Date Dec. 11, 1998 PCT Filed Feb. 19, 1997 PCT Pub. No. WO97/30740 PCT Pub. Date Aug. 28, 1997A pump comprises variable volume means inserted in an artery, in particular, the descending aorta, enabling the volume through which the blood flows in this location to be modified cyclically and in a controlled manner. The device comprises a deformable enclosure in fluid communication with the variable volume. The variable volume and a spring coil urge the deformable enclosure against an increase of volume resulting from a pressure increase in the variable volume, and in the corresponding enclosure, in a way which produces additional elastance for the artery during the heart cycle. In addition, an electric motor can control the deformable enclosure to increase or decrease its volume, and can exert its force in addition to or in subtraction from the force of the spring coil during the systolic and diastolic phases of the heart cycle. This produces an additional pumping effect on arterial blood and correspondingly relieves the effort required of the heart.
